Haven't read the other comments, my 2 cents: We use OKRs as the only way to set strategies in circles (so, LL's make it, but only for their own circle, not for the roles within it). Currently we have 1 O and 1 KR for the organisation as a whole, but average it's been 2/3 O's and each 2/3 KR's. This is the same for each circle. 

Usually KRs are metrics (but there are many more metrics than KRs), and there are numerous projects to support them.
